TR-01 Rotary Engine Compression Tester - Official Group Buy
The TR-01 is a digital hand-held rotary engine compression tester available as a more affordable option compared to similar testers already on the market. It utilizes a powerful micro-controller and a 0-200psi pressure transducer to detect the three distinct compression pulses of a rotary engine. These pulses, along with RPM, are then displayed on the back-lit LCD.
http://www.twistedrotors.com/images/tr01_blue.JPG Group Buy price is set at $230 for each unit. You have a choice of either a blue or green LCD, please specify which color you'd like when you order. From testing I can say that the green LCD is easier to see in daylight, but the blue just looks slick! I need at least 10 orders to get this started. Shipping will be via USPS Priority Flat-Rate mail and includes insurance. Unit price includes shipping to U.S. Addresses. Additional shipping required for non-U.S. Addresses is $37 ($21 to Canada). Payments via Paypal: TR01@TwistedRotors.com (that is TR<zero>1) Ensure that your shipping address in Paypal is correct and please include your forum name with the payment. This Group Buy price will be good for 2 months, so get them while they're cheap! As an incentive, during this GB I am offering an optional splash screen personalization for each unit. Upon power up, your unit will display the standard TR-01 splash screen with firmware version. http://www.twistedrotors.com/images/tr01_splash.JPG Then a personalized screen with your name will be displayed. http://www.twistedrotors.com/images/tr01_name.JPG Original thread https://www.rx8club.com/series-i-tech-garage-22/new-compression-tester-handheld-digital-165870/ Testing a “blown” 13B-REW http://www.youtube.com/watch?v=dZG28b05H9k Testing HeavyMetal699's RX-8 http://www.youtube.com/watch?v=4IjZH2Xongw Technical Data: Display: 16x2 LCD, back-lit (blue or green) Maximum pressure reading: 200psi Minimum pressure reading: 10psi Measurement accuracy: <1% FS Measurement time: <1.0 msec Power source: 9 volt battery Dead volume has been calculated and the correction factors are listed below. I decided not to code in an automatic correction as the number varies slightly depending on the engine type. For reference the internal volume of the sensor (with adapter) is 2.85cc. To correct for the sensor dead volume just multiply your readings by the correction number appropriate for your engine. Engine Year Ratio Correction 12A 76-82 9.4 1.042 12A 83-85 9.4 1.042 13B 74-78 9.2 1.035 13B 84-85 9.4 1.036 13B N/T 86-88 9.4 1.036 13B T 86-88 8.5 1.032 13B N/T 89-92 9.7 1.038 13B T 89-92 9.0 1.034 13B T/T 93-95 9.0 1.034 13B Ren 04-on 10.0 1.039 Warranty: The tester is covered for a period of 2 years from date of purchase. I will repair/replace any units that fail due to any defect in my manufacturing. Basically if it isn't broken due to abuse or misuse then I will fix it. Note that this does not include the sensor which will have to be on a case-by-case basis. These pressure transducers are heavy duty units designed for industrial applications so failure is highly unlikely. In the event that a sensor does fail I will work with the customer to get a replacement from the sensor manufacturer. With all that said, if you were to accidently damage your tester then let me know. I can work with you to get your unit repaired, I plan to keep repair parts/spare units for at least 5 years. I want everyone to be happy with their TR-01! 1. Texak - RX8Club - Blue LCD, "Property of ; Texak" - Payment Received, thanks! 2. Gvang - RX8Club - Blue LCD, "H.T.T.S. ; N.

You made it! w00t w00t:rock:
|
Good stuff.
|
Put me down for a blue lcd one! when can I send the money?
|
Accepting payments at this time. Make a note that you'd like a blue LCD in Paypal and what name you'd like on your personal splash screen. Thanks!
-John |
some1 in jax needs to buy one.
|
I'm getting mine Thursday
|
Paypal sent!!! When will you be shipping them out?

Damn.. might change my delivery location then. i leave town in 2 weeks. I was hoping to test the compression before i left so I could leave the car with the dealership. Nothing you can do about that though.

So for messages I will do any message you'd like, as long as it's "appropriate"...however there are space limitations. The screen is 16x2 characters and your message must fit within that. -John Texak, let me know if you'd like to change your message. :-) |
:yumyum:
I am very much on the fence about committing to this. I do not see myself really *needing* it so much as I am just curious about knowing what my engine would actually put out. I am rather neurotic about the health of the engine even though I have yet to have any cause for concern with the lack of issues. Regardless, kudos to you for making this tester! Consider this my subscribing to the thread and trying to convince myself to get it! |
John,
I am interested in 2 units. Do I calculate the shipping price X2 or do you have something like combined shipment? Regards, George |
just found this.
john you have another pm coming.. :) btw, could my splash screen say? please be good! :lol: beers scott |
PM Sent
BTW: What are the MAXIMUM Characters allowed for the 'splash screen' including spaces. |

Regards, George The shipping method I'm using for the International folks will not change for 2 units. I can fit them both in the same box. So for 2 units you're looking at $497 USD shipped.

OK, by my count that is 8 or 9 paid... c'mon, only 2 more people!!! I want this thing soon!
|
Updated first post. We're off to a great start!!
-John |
Would this work on the 16x?
The chamber is different. I'm thinking it would have to be calibrated for that. |
PayPal sent for one more!

If we order these now, will we be eligible for software updates when you release them (which I am sure is going to happen at some point for one reason or another)? Can we do the updates ourselves or would we have to ship the units back?
|
payment sent

what updates? the correction factor is just a table you can use to calculate by hand...

Been working in software for 10 years and I've never seen a product go out at 100%. It just doesn't happen. Nature of the beast. |
this is pretty cool. I'm still under warranty tho
|
Dam, need one more buyer so Twisted can get started.

Getting this will give you an engine compression baseline. If you test regularly you'll know if your engine is beginning to fail or not. Knowing that your engine is failing will help you know when to 'gamble' on a compression test by Mazda. |

I have payed for but not received my compression tester yet. Is there some issue?
I JOKE! I TEASE! |
How to Perform Compression Test - From Mazda Factory WS Manual Series II RX-8's
1. Remove Engine Cover.
2. Verify that Battery is fully charged. 3. Warm Up Engine. 4. Remove the Trailing or Leading Spark Plug of the front and rear rotors. 5. Disconnect Eccentric Shaft Position Sensor (Crank Sensor). WARNING: Hot engines can cause severe Burns. CAUTION: To cut the fuel injection and ignition, make sure the Eccentric Shaft Position Sensor (Crank Sensor) is Disconnected. TO TEST COMPRESSIONS. 1. Install TR-01 Spark Plug Sensor to the Trailing or Leading side Spark Plug Hole Of The Rotor Housing. 2. Depress the Accelerator pedal fully and crank for 7 seconds or more. 3. Read Compressions and Engine Crank Speed (RPM). 4. Perform the same procedure for the other Rotor Housing. 5. If the compressions is at the minimum or less, or the difference in the chambers and difference in the rotors exceed the specifications, replace or overhaul engine. SPECS RX-8 2009 Model. Standard : 830kPA 8.5kgf-cm, 120 PSI @250RPM Minimum : 680kPA 6.9kgf-cm, 98.6 PSI @ 250RPM Standard Difference Between Chambers: Within 150kPA 1.5kgf-cm, 21.8 PSI Standard Difference in Rotors: Within 100kPA 1.0kgf-cm, 14.5 PSI 6. Install Spark Plugs (correct heat ranges - Leading or Trailing). 7. Connect Eccentric Shaft Position Sensor (Crank Sensor). 8. Install Engine Cover. As I do not have the Series I Factory Workshop Manual I can't verify the details are the same (I would assume they are as the internals (Seals, ETC) of the 2 RENESIS's have not changed). |
Just watched TR's videos, and a "related" one that popped up of a Japanese company using the Mazda one on a '92 FD. I'm absolutely in. Ordered.
